United States Patent 3,442 461 CONE WINDING MACI'IINE FOR SPINNING Jorge Marti Sola, Calle Cataluna 108, Tarrasa, Barcelona, Spain Filed Nov. 10, 1965, Ser. No. 511,019 Int. 'Cl. B65h 63/02; B65 63/04 US. Cl. 24237 4 Claims ABSTRACT OF THE DISCLOSURE This invention refers to a cone winding machine for spinning, with which it is possible to achieve that each winding unit works independently from the other units which form the machine and also that the various units which form the machine be installed on the same rotary bench so that all may be attended to by only one worker from one working position, which provides economy in the use of power and in the cost of labour.

At present, the known cone winding machines consist of a plurality of cone-carrier shafts, all of them moved by a transmission, Worked in turn by an electric driven motor. In other types of machines, the transmission moves a plurality of thread guiding, grooved cylinders, for as many cone-carriers as the machine may have, which make the cones turn by friction.

In these known machines, when the thread corresponding to any cone breaks, it is necessary that the worker stop the machine to knot it and, consequently, all the guiding cylinders and all the cones are stopped, i.e., the working of the whole machine is paralysed. Also, these machines always produce the winding of all the cones with equal thread length, and it is not possible to wind one or more cones with different lengths of thread.

It is an object of the invention to avoid said inconveniences by, providing a machine in which each winding unit has independent working means, allowing regulation of its speed within very ample limits independently from the speed with which each of the other independent windin g units which form the machine may work.

It is another object of the invention to provide a cone winding machine for spinning in which each winding unit produces a cone with a pre-determined amount of wound thread and, on reaching said amount, the Winding unit stops automatically, independently from the other winding units which continue working.

It is still another object of the invention to provide a cone winding machine for spinning in which, when the thread which is being wound on a winding unit breaks or runs out, the latter stops automatically, without stopping the other winding units which form the machine.

It is another object of the invention to provide a cone winding machine for spinning in which the autonomous winding units are mounted on a platform which can be turned on one and the same horizontal plane so that only one worker can attend to the working of all the winding units without having to move from his work position.

These and other objects are achieved with the cone winding machine for spinning, according to my invention, and will be easily understood by any person who is an 3,442,461 Patented May 6, 1969 expert in spinning techniques, by reading the following description of the drawings which are enclosed with this specification, in which:

FIGURE 1 shows a side view of a winding unit.

FIGURE 2 shows the same unit seen at ninety degrees from the representation of FIGURE 1, and with part of the motor cross-sectioned.

FIGURE 3 is a top view of a rotary table carrying several winding units,

FIGURE 4 is a side view of the same table.

FIGURE 5 is an enlarged side view, partly in section, of the device raising the cone.

In the drawings, 1 is the elective driven motor of the winding unit, which, on its rear part carries the cover 2. Fixed on the side of the housing of the motor 1 are the bearings 3 in which the shafts 4 of the crank arm 5, 6 are installed, the shaft 4 being prolonged on the rear part to receive the handle 7 with which this crank arm can be turned about the shaft 4 by hand. Mounted in the housing 1 is the adjustable stop 8 which supports one of the branches 5 of the crank arm in its high position, which is that represented in FIGURES 1 and 2, so that in this position the crank arm does not extend completely vertically. The thread to be wound on the cone comes from a bobbin situated on the lower part of the platform. When the thread breaks, the crank arm 5, 6 under its own weight, oscillates downward and occupies its lowest position, in which its cam 9, which is mounted upon the shaft 4, acts on the stopping switch as is described later on.

The shaft 10 of the electric driven motor has the triple pulley 11, 12 and 13, fixed in an easily dismountable way; installed on the housing of the motor 1 are the brackets, 14, 15, 16 and 17, between which is installed the thread guiding grooved cylinder 18 on its shaft 19, there being installed on the end of this shaft the triple pulley 20, 21 and 22, which can also be easily dismantled. These pulleys and those of the motor are made with diameters which are complementary in order to link them by installing a coupling belt, not represented. The diameter of the pulley 13 is greater than that of 20, that of 12 is greater than that of 21 and that of pulley 11 greater than that of 22, so by changing shafts, these two triple pulleys, i.e., by installing triple pulley 11, 12 and 13 on the shaft 19 of the thread guide 18 and the triple pulley 20, 21 and 22 on the shaft 10 of the motor 1, different speeds are obtained for the cylinder 18 for the same speed of the motor 1 and, thus, in the case represented it allows the obtaining of six different speeds in the thread guiding cylinder 18.

On the thread guiding cylinder 18 is mounted the cone 23 which has the neck 24, as in the known cones, and is fixed articulately with possible regulation of position between plates 25 by the shaft 26, which is extended at 27 to end in a blunt conical point 28, on which the spring 29 is applied to keep it in the proper position, i.e., on the thread guiding cylinder 18. The shaft 26 is provided with the rod 30 which, as is seen in FIG. 2, ends in the handle 31 so that it may be operated, not only making it turn but also raising it. The plates 25 are joined to the end of the bar 32 which is mounted in the sleeve 33, at an axially adjustable position so that the location and position of the shaft of the cone may be adjusted in relation to the thread guiding cylinder. The shaft 26 also extends through the plates 25. By operating the handle 31 connected to the rod 30, the shaft 27 and the core 23 can be rotated. The spring 29 can press against the end 28 of the shaft 27 to maintain the shaft 27 perpendicularly to the bar 32. When the end 28 of the shaft 27 is not in contact with the spring 29, the shaft 27 and the cone 23 are in a position in which they constitute an extension of the bar 32. Then the cone, the winding of which has been completed, is removed from the shaft 27 and is replaced by a new one. The sleeve 33 is joined to the disk 34 which is mounted on the shaft 35, eccentrically located in relation to the outline of the disk itself, and which is carried upon the bracket 36 which in its lower part 37, is extended horizontally to be fixed by members 38 to the electric driven motor 1. The bracket 36 carries a ball 39 pressed by spring (not shown) against the disc 34; when the disc 34 is turned the ball 39 enters into a recess 40 in the disk.

As the shaft 35 is made eccentric in relation to the disk 34, when this disk 34 turns, its periphery takes up contact with the feeler 41 of the lever 42 which governs the switch 43 and opens its electric circuit, the motor being disconnected and stopped. As the cone 23 is permanently supported on the thread guiding cylinder and as the latter receives spirals of thread, its diameter increases and, accordingly, the shaft of the cone separates itself from the thread guiding cylinder. Then the bar 32 will rise little by little until the periphery of its eccentric disk 34 comes into contact with the feeler 41, which as has been indicated, produces the stopping of the motor. For this, the switch 43 is fixed on the stable point 44 and on the variable point 45, which is formed by the arched groove 46, with its center on 44, and thus it is possible to adjust the position of this switch so that when the cone has received a predetermined amount of thread, the eccentric disk 34 may act on the feeler 41 and stop the working of the unit, also producing said stopping of the working of the motor when the bar 32 is raised.

Each winding unit also has a device which produces the stopping of the motor when the thread breaks or runs out and this is achieved by means of the crank arm 5, 6, on whose upper branch 6 the thread is supported and retained in the represented position, in which the cam 9 is compressing the pin 47 which traverses the motor housing 48 and whose inner end has moved the contacting sheet 49 which is fixed by the insulations 50 and 51 inside the motor housing. The contacting plate 53 which, in the position represented comes into contact and closes the electric circuit with contact 54, is fixed on 55. When the thread breaks, the crank arm 5, 6 turns on its shaft 4 by its own weight, as the stop 8 prevents it from exceeding or reaching the vertical plane of the shaft 4 and, on turning, its cam 9 offers its part of lesser diameter for contact with the stem 47 and the elastic action of the sheet 49 moves it outwards, the contacting plates 53 and 54 being separated and the electric circuit opened, producing the stopping of the electric driven motor.

These winding units are also completely independent and of automatic operation, both when the thread breaks and when the cone has already wound the pre-determined amount of thread, the stop automatically and, for the handling and watching of the operation by only one worker, various winding units are fixed on the table 56, see FIGURES 3 and 4, which, in this case, has a hexagonal top to receive the installation of six winding units. This table or bench is provided with the stem 57 with the collar 58 which is held by its end 59, with the possibility of turning, in the column 60 of the foot 61 which is fixed to the floor. A bobbin carrier 62 and the plate 63 are mounted in the collar 58 and in correspondence with each winding unit. Also installed in correspondence with each winding unit is a paraffin coating device 64 and a guide pin 65, being completed with a guide 66 for the thread. These devices are well known in the art and are indicated merely diagrammatically. In the base is installed the pedal 67 which brakes and holds the table in any position when turning on the shaft 59, with which one person alone, without moving from his work position, can attend to the operation of each and every one of the units just by pressing the pedal and making the platform turn. In this case, six winding units are installed, but it can have more or less than six. The table can be turned manually or by any suitable mechanical means.
